RESUMEN

The study objective was to determine the prognostic value of assessment of staining of p53 and bcl-2 in a well-selected group of serous ovarian carcinomas. Immunohistochemical detection was used to identify both p53 and bcl-2 positive tumors. One hundred thirty-two tumors were analyzed for positivity of staining, grade of staining intensity, and for p53 alone, percent expression rates. These were analyzed alongside traditional clinicopathologic parameters for their ability to predict overall survival (OS), disease-free survival (DFS), and response to chemotherapy (CR). Univariate COX analysis revealed percent p53 expression (P = 0.012) and p53 grade (P = 0.01) to be significant predictors of DFS. Neither the p53 nor bcl-2 measurement parameters were found significant for OS or prediction of CR. On multivariate analysis, incorporating clinicopathologic parameters, p53 parameters did not retain independent significance for any outcome measure. As in primary reported studies, bcl-2 was not found to be of clear independent prognostic value in this group of ovarian tumors. If mutation of p53 and its consequent overexpression is an early event in ovarian tumorigenesis, then p53 assessment may prove useful prognostically in the assessment of either low-grade ovarian carcinomas, as a possible indicator for progression, or in early-stage ovarian tumors, as a marker of tumor aggression or likelihood of recurrence. p53 analysis of a larger group of stage I ovarian tumors would be desirable to further explain the potential association with DFS.

RESUMEN

The objective of this study was to determine whether nuclear morphometric data can predict survival, disease progression, and chemotherapeutic response in ovarian serous carcinoma. Nuclear morphometric parameters were determined from archival hematoxylin and eosin sections of 132 serous tumors. Clinicopathologic and morphometric parameters were evaluated as to their individual and independent prognostic value and prediction of chemotherapy response. Nuclear parameters were found to strongly correlate with extent of disease residuum, tumor grade, and FIGO stage. Univariate analysis revealed stage, grade, preoperative CA125, presence of ascites, extent of disease residuum, standard deviation of nuclear area (SDNA), nuclear perimeter (NP), SDNP, nuclear length (NL), nuclear breadth (NB), orthoferet, and equivalent diameter (ED) to be significant predictors of overall survival (OS) and disease-free survival (DFS). Grade, stage, extent of disease residuum, presence of ascites, SDNA, NP, NL, NB, and orthoferet were found to be significant predictors of chemotherapy response. Multivariate analysis revealed extent of disease residuum (P

RESUMEN

Müllerian metaplasia of the female genital tract is usually of limited extent and subtype. We describe the replacement of the lining of the entire genital tract and much of the overlying pelvic serosa by metaplastic müllerian epithelium, in a nulliparous 65-year-old woman with cervical agenesis. She did not have Peutz-Jeghers syndrome and had not had any form of prior hormonal treatment. The metaplastic epithelium extended from the vagina to the serosal surface of the pelvic organs. Mucinous epithelium predominated. In addition, there was multifocal dysplasia of the metaplastic epithelium; this was most prominent in the fallopian tubes where there was marked papillation with cytoarchitectural features reminiscent of a borderline mucinous ovarian tumor. Although müllerian metaplasia is well recognized at different sites within the female genital tract, this highly unusual finding of multiple metaplastic epithelial subtypes and dysplasia involving the mucinous metaplastic epithelium along the entire genital tract and pelvic serosal surface has not, to the best of our knowledge, been reported previously in the absence of Peutz-Jeghers syndrome.

RESUMEN

The objective of this study was to assess the adequacy of network cancer guidelines paying particular attention to referral criteria, referral routes, tumor diagnosis, staging, and suggested management and care pathways for ovarian and endometrial cancer. Guidelines from 15 regions in England and Wales were analyzed quantitatively and qualitatively as a prospective audit of predefined data items and subsequently agreed management recommendations. Details of unit and center clinicians were included in a minority of documents (2 to 5/15). Multidisciplinary team membership was not usually offered (6/15). Among the least reported data items were histopathology minimum dataset for endometrial cancer and an algorithm for management or summary and clinical symptoms and signs for both cancers. Among the most reported data items were hysteroscopy and ultrasound scanning for endometrial cancer and CA125 and chemotherapy for ovarian cancer. Qualitative analysis revealed differing criteria for the use of endometrial biopsy and radiotherapy in endometrial cancer, for lymphadenectomy and management of recurrent disease in ovarian cancer, and for referral pathways and the use of computed tomography/magnetic resonance (MR) scanning in the assessment of either disease. This study concludes that consideration should be given to the development of national guidelines or templates to ensure consistency of management for gynecological malignancy in England and Wales.

RESUMEN

BACKGROUND: Ovarian angiosarcomas are rare tumors which may to be distinguished from other unusual primary ovarian tumors such as clear cell carcinoma, yolk sac tumor and leiomyosarcoma on the basis of histological appearance and immunohistochemistry. Angiosarcomas of the ovary occur in all age groups but are more frequent in women of child bearing age (less than 40 years). Surgery and radiotherapy have been the traditional treatment modalities. CASE: The case we present is the only reported long-term survivor of recurrent ovarian angiosarcoma. Her initial treatment was surgical, both at presentation and relapse but since she wished conservation of fertility, radical surgery and radiotherapy were avoided and she underwent further adjuvant chemotherapy with doxorubicin and ifosfamide. She remains in remission 6 years after treatment of recurrence of the primary tumor and has had a successful pregnancy following treatment. CONCLUSION: Adjuvant chemotherapy of ovarian angiosarcoma with a combination of doxorubicin and ifosfamide appears effective and should be considered in women at risk of relapse who wish to conserve fertility.

RESUMEN

Infection with high-risk genital human papillomavirus (HPV) types is a major risk factor for the development of cervical intraepithelial neoplasia (CIN) and invasive cervical carcinoma. The design of effective immunotherapies requires a greater understanding of how HPV-specific T-cell responses are involved in disease clearance and/or progression. Here, we have investigated T-cell responses to five HPV16 proteins (E6, E7, E4, L1 and L2) in women with CIN or cervical carcinoma directly ex vivo. T-cell responses were observed in the majority (78%) of samples. The frequency of CD4+ responders was far lower among those with progressive disease, indicating that the CD4+ T-cell response might be important in HPV clearance. CD8+ reactivity to E6 peptides was dominant across all disease grades, inferring that E6-specific CD8+ T cells are not vitally involved in disease clearance. T-cell responses were demonstrated in the majority (80%) of cervical cancer patients, but are obviously ineffective. Our study reveals significant differences in HPV16 immunity during progressive CIN. We conclude that the HPV-specific CD4+ T-cell response should be an important consideration in immunotherapy design, which should aim to target preinvasive disease.

RESUMEN

AIMS: To describe the clinical and pathological features of 12 further cases (in 11 patients) of superficial cervicovaginal myofibroblastomas (SCVM), rare tumours that hitherto have been described only in a single series of cases involving the cervix and vagina. METHODS AND RESULTS: The patients' ages ranged from 23 to 80 years. Ten tumours were located in the vagina and two in the vulva. Three patients had been taking tamoxifen. The tumours ranged in size from 2 to 45 mm and morphologically were well-circumscribed lesions composed of bland ovoid to spindle-shaped cells, often with wavy nuclei. These cells were arranged in a variety of architectural patterns and were set in a finely collagenous stroma. Five cases exhibited stromal oedema or myxoid change and in eight cases hyalinized areas with thick, dense collagen bundles were present. Immunohistochemically, there was positivity with vimentin (11 of 11 cases tested), CD34 (six of 12 cases), desmin (nine of 12 cases) and oestrogen receptor (nine of 11 cases). All cases tested were negative for smooth muscle actin, S100, h-caldesmon, HMB45, and CD31. In this study we expand on the morphological spectrum of these rare lesions and reiterate their association with tamoxifen. CONCLUSIONS: Since these lesions may occur on the vulva, as well as the cervix and vagina, we propose the term 'superficial myofibroblastoma of the lower female genital tract'.

RESUMEN

AIMS: Cellular angiofibroma (CA) is a rare benign mesenchymal lesion with a predilection for the vulval region. In this report we aim to describe the clinical, pathological and immunohistochemical features of a series of vulval mesenchymal lesions, some of which have the classically described histological appearance of CA while others exhibit atypical features. We believe these lesions fall within the broad spectrum of fibromatous lesions of the vulva. METHODS AND RESULTS: Seven cases were included. Histological sections were examined and immunohistochemical staining with vimentin, desmin, alpha smooth muscle actin, h-caldesmon, S100, EMA, AE1/3, CD34, CD10, ER, PR and MIB1 was performed. The patients' ages ranged from 20 to 65 years and the lesions ranged in size from 10 to 50 mm. All lesions were well circumscribed, moderately cellular lesions and were composed of bland spindle-shaped cells set in a fibrous stroma. Many blood vessels with thick hyalinized walls were present in four cases, in one case occasional such blood vessels were present and in two cases vessels with thick hyalinized walls were not present. In five cases the vessels were at least focally dilated resulting in a haemangiopericytomatous pattern. Histological features identified in a variable numbers of cases included peripheral adipose tissue (four cases), adipose tissue within the centre of the lesion (one case), stromal mast cells (six cases), stromal lymphoid aggregates (five cases), scattered multinucleate cells (five cases), hypocellular hyalinized areas (two cases), myxoid areas (four cases) and focal areas of marked cellular atypia reminiscent of symplastic change within a uterine leiomyoma (one case). Mitotic figures were identified in four cases, all with a mitotic count of < 1 per 10 high-power fields. Immunohistochemically all neoplasms were positive with vimentin and all but one with ER and PR (PR staining was not performed in one tumour). In all cases desmin, alpha smooth muscle actin, h-caldesmon, S100 and AE1/3 were negative (h-caldesmon and AE1/3 staining were not performed in one case). Three cases were positive with CD34, one with EMA and two with CD10. All exhibited a low MIB1 proliferation index of approximately 1%. One lesion recurred locally 6 months following initial removal. CONCLUSIONS: CA is a rare benign vulval mesenchymal lesion with limited potential for local recurrence. We describe several hitherto unreported histological features which add to the morphological spectrum. Although not all lesions exhibit the classically described histological features of CA, we believe all fall within the broad spectrum of benign vulval fibromatous lesions. These cases are characterized by vimentin positivity but negative staining with smooth muscle markers which assists in excluding many of the other vulvovaginal mesenchymal lesions which enter into the differential diagnosis. The immunophenotype indicates that CA probably exhibits fibroblastic rather than myofibroblastic differentiation. These lesions are almost always positive with ER and PR, suggesting that they probably arise from the hormone receptor-positive subepithelial mesenchymal layer within the lower female genital tract.

RESUMEN

Smooth muscle tumours of the uterus are common and the majority are benign leiomyomas. However, there are some tumours which exhibit unusual morphological features or growth patterns that cause difficulty in their distinction from malignant neoplasms and those with endometrial stromal differentiation. Such lesions are reviewed in this article with detailed descriptions of their morphology, differential diagnosis and correlation with biological behaviour.

RESUMEN

BACKGROUND: Laboratory and epidemiological research suggests an association between human papillomavirus (HPV) and cervical intraepithelial neoplasia (CIN). We studied the natural history of incident cervical HPV infection and its relation to the development of CIN. METHODS: We recruited 2011 women aged 15-19 years who had recently become sexually active. We took a cervical smear every 6 months and stored samples for virological analysis. We immediately referred all women with any cytological abnormality for colposcopic assessment, but postponed treatment until there was histological evidence of progression to high-grade CIN. FINDINGS: In 1075 women who were cytologically normal and HPV negative at recruitment, the cumulative risk at 3 years of any HPV infection was 44% (95% CI 40-48): HPV 16 was the most common type. The cumulative risk at 3 years of detecting an HPV type not present in the first positive sample was 26% (20-32). 246 women had an abnormal smear during follow-up, of whom 28 progressed to high-grade CIN. The risk of high-grade CIN was greatest in women who tested positive for HPV 16 (risk ratio 8.5 [3.7-19.2]); this risk was maximum 6-12 months after first detection of HPV 16. All HPV types under consideration were associated with cytologically abnormal smears. Although abnormality was significantly less likely to be associated with low-viral-load samples, the cumulative risk at 3 years of a high-viral-load sample after a low-viral-load sample was 45% (95% CI 35-56). Five women who progressed to high-grade CIN consistently tested negative for HPV. INTERPRETATION: Our findings suggest that attempts to exploit the association between cervical neoplasia and HPV infection to improve effectiveness of cervical screening programmes might be undermined by the limited inferences that can be drawn from the characterisation of a woman's HPV status at a single point in time, and the short lead time gained by its detection.

RESUMEN

Forty-six cases of vasculitis affecting the female genital tract are described; only 41 similar cases have been previously reported, either as case reports or small series. The age range of the patients was from 22 to 80 years, and most of them presented with abnormal bleeding or were being treated conditions unrelated to the vasculitis. There were 39 hysterectomy specimens (26 of which were derived from total abdominal hysterectomies) and seven specimens of the cervix only. The vasculitis was confined to the cervix in 30 of the 46 cases; in 24 of these, the entire uterus was available for examination. In 23 cases, only a single vessel was involved, and in the other 23 there was more extensive vessel involvement. In all cases, the involved vessels were arterioles and small arteries. In 42 cases, the arteritis was of the polyarteritis nodosa (PAN) type, and in four, of the giant cell type (GCA). Follow-up ranged from < 1 year to 23 (mean, 3) years. Systemic manifestations were previously diagnosed or subsequently developed in only four patients, three with PAN and one with GCA; in each of them, the genital tract vasculitis was found only in the cervix (in one of these, however, the specimen was a loop excision of the cervix and the rest of the uterus was not assessable). The three patients with PAN subsequently developed extragenital PAN (one case), PAN and rheumatoid arthritis (one case), or PAN and polymyalgia rheumatica (one case). The patient with GCA had previously documented temporal arteritis and temperomandibular arthritis. The findings in this series and in previously reported cases indicate that vasculitis of the female genital tract is only rarely associated with systemic vasculitis.

RESUMEN

We report the case history of a patient with a family history of breast and ovarian cancer who was subsequently found to be a carrier of the BRCA1 gene, in whom a tiny focus of clear cell carcinoma was found at the fimbrial end of one fallopian tube when she underwent prophylactic hysterectomy and bilateral salpingoophorectomy. The implications of this finding are discussed.

RESUMEN

Apoplectic leiomyoma is a distinctive smooth muscle tumour usually occurring in women either taking oral contraceptives or who are pregnant or recently postpartum. Most of these tumours show 0-2 mitoses per 10 high power fields, but a mitotic index of up to 8 per 10 high power fields is allowed in such tumours. We describe an apoplectic leiomyoma with a number of atypical features including a high mitotic index (up to 20 per 10 high power fields) in a 47-year-old woman. Follow-up clinically and by computerised tomography (CT) for 3 years demonstrates no recurrence.
